The research team led by Dr. John Thayer from the Department of Ophthalmology and Epidemiology compared the eating habits of 876 people aged between 55 and 80, of whom 356 were macular degeneration patients and 520 were not. They found that the more carotenoids are absorbed, the smaller the risk of macular degeneration. Lutein and zeaxanthin, two carotenoids in green vegetables, are the most effective.
